Distributors can be reclocked to make room for vacuum modules and interference issues. Pull it up, rotate it one or two teeth in the direction you need, start the engine and reset the timing.
Let me elaborate a bit. Before you move it, take the cap off and use a sharpie to mark the location of the rotor on the top edge of the dizzy housing. Pull up and reclock the housing where you need it but make sure when it's fully seated, the pointer is aiming at the mark you made earlier. It might take a couple tries to get everything lined up due to the way the gears are cut. Once your happy with everything, snug it down, start it up and reset the timing.
